Thumb sucking figures

Last month I got a bill of over R400 from neotel and obliged even though I did not use their service for half the month. I then had connection problems from the beginning of the which I drove to the store 50km far from my home twice to sort out and was told a technician would be sent to my house but have since been waiting.Now here is my argument I haven't been sent usage figures even though through my two visits I asked the consultant to make sure I get notified (no luck there)Secondly how is it that I got to over R600 when I was told at the cap was around R400. Please can sum1 explain this to me. I just think they thumb suck figures if I have to pay so much for not even half the month then please come get your device I don't need such.
